OTTO I-I. WANDERSEE, OF ROCHESTER, NEW YORK.

REPRODUCER FOR TALKING-MACHINES.

To aZZ whom it may concern:

Be it known that I, OTTO H. WANDnnsnn, a citizen of the United States, and resident of Rochester, in the county of Monroe and State New York, 'have'invented certain new and useful Improvements in Reproducers for Talking-Machines, of which the following is a specification.

The present invention relates to reproducers for talking machines and more particularly to the mounting of the stylus lever, an obj ect of this invention being to provide a mounting which may be readily changed to obtain different tones from the reproducer.

To this and'other ends, the invention con-- sists of certain parts and combinations of all of which will be hereinafter described, the novel' features being pointed out in the appended claims. 1

Figure 1 is a plan view, partially in section, of a'reproducer embodying the present invention; f

Fig. 2 is an edge view of the reproducer partially in section;

Fig. 3 is a section through one of the blocks employed for supporting the stylus lever, the section being taken on the line 3-3, Fig. 4. i. I

Referring more particularly to the drawings, 1 indicates the reproducer casing or Specification of Letters Patent. Patented J 11119 '2, 1921. Application filed July 7, 1920. Serial No; 394,433. 2

housing and 2 the diaphragm which has a stylus lever 3 secured thereto at the center thereof at 4 and provided with a. clamp 5 for holding the stylus 6. I

WVith the end in view of mounting the stylus lever '3 on the casing 1, twov blocks 7 are provided which rest upon seats formed on the ears 8 on said casing 1, said ears also having shoulders or abutments 9 engaged by the blocks at the sides of the latter. Each block is preferably held to its seat against the shoulder by a screw 10 passing through an ear 8 and into an opening 11 formed in the under side of the block. The blocks are also provided each with a central opening 12 and a slot or pocket 13 intersecting said central opening and also the bottom face of the block. A sounding piece 14 made of wood, hardrubber, metal or any other desired material, is inserted in this pocket 13 for the purpose of providing a support for the stylus lever.

In order to support the stylus lever on the sounding pieces 14, the stylus lever preferably has arms 15 projecting in opposite directions from the sides thereofand provided with screw threaded openings 16 in their ends. Into these screw threaded openings are secured extensions each of which comprise a screw threaded portion 17 fitted in a screw threaded opening 16, a reduced cylindrical portion 18 adapted to rest in a seat 21 formed in a sounding piece 14, a shoulder 19, and a portion 20 of rectangular cross section. Each extension is also provided at its end with a slot 22 in which a screw driver or other tool may be introduced for the purpose of drawing the shoulder 19 firmly against one face of the sounding piece 14 so that the arms 15 are supported under tension on the two sounding pieces 14. In

order to hold the arms 15 on the two sounding pieces, each block 7 has a set screw 25 passing through the top wall thereof and engaging the cylindrical portion 18 of the extension in line with the plane-of the sounding piece 14. Each block also has a set screw 24 for engagement with the portion 20 of the extension, a piece of rubber 25 or other sound deadening materialpreferably being interposed between the screw 24 and i the extension.

Instead ofnsing the sounding pieces 14 the stylus lever may be supported on knife edges in the manner illustrated in Figs. 11 to 14 inclusive and to this end the extensions are each provided with a longitudinally ex tending slot 26 which, when the extensions are screwed tightly in the arms 15, face toward the diaphragm 2: One of the side walls of each of the blocks 7 has a screw 27 mounted therein and provided with a knife edge 28 which projects into the slot 26. The opposite wall of the block 27 has ascrew 29 which cooperates with the opposite side of the extension, a sound'deadening piece 30 being preferably interposed between the screw 29 and the extension. This arrangement provides a knife edge mounting of the arms 15 on the housing of the reproducer.

From the foregoing it will be seen that there has been provided a reproducer in which the stylus lever is supported in blocks in such a manner that the lever may be adjusted to obtain various mountings therefor. The stylus lever ias extensions, which in one instance adjustable to produce a tension on the sounding pieces and in another instance are firmly held to the lever so that a knife edge mounting of the lever may be obtained.

lVhat I claim as my invention and desir to secure by Letters Patent is:

l. The combination with a reproducer casing and a stylus lever having arms projecting from opposite sides thereof, of adjustable extensions mounted in said arms and having abutments thereon and sounding pieces on which said adjustable extensions are held, said sounding pieces being engaged by said abutments.

2. The combination wi th reproducer casing and a stylus lever having laterally extending arms, of a pair of extensions adj ustable in said. arms'and provided with abutments, sounding pieces on which said extensions areheld, said pieces being engaged on the sides by the abutments, and removable blocks secured to the reproduccr casing and supporting said sounding pieces.

3. The combination with a reproducer casing and a stylus lever, of seats on said casing, shoulders adjacent said seats, blocks held to the seats and having central openings ano slots intheir oottom walls intersecting aid openings, sounding pieces ar ranged in said slots, and adjustable extensions on the stylus lever held to said sounding pieces.

4. The combination with a reproducer casing and a stylus lever, of seats on the casing, shoulders adjacent said seats, blocks resting on said seats'against the shoulders and having central openings and pockets extending through the under laces and n1- tersecting saidcentral openings, sounding comprising sounding pieces on wh ch said extensions rest, and screws for holding said extensions in cooperation with said sounding pieces.

The combination with a reproducer casing, of blocks removably secured to said casing, sounding pieces removably arranged in said blocks, a stylus lever, and adjustable extensions carried by said stylus lever and held to said sounding pieces.

8. The combination with a renroducer casing, of sounding pieces arrangedon said casing, a stylus lever, and adjustable extensions having screw 1 threaded "engagement with said lever, held to said sounding pieces and having surrounding shoulders engaging the sides of said sounding pieces.

9. The combination with a reproducer "casing, of sounding pieces arranged on said casing, a stylus lever, adjustable extensions having screw. threaded engagement with said stylus lever, bearing on said sounding pieces and having annular shoulders engaging with said sounding pieces, and screws for holding said adjustable extensions against the sounding pieces.

10. The combination with a reproducer casing and'a stylus lever, of blocks on said casing having openings, extensions on the stylus lever projecting into said openings,

and means arranged on said blocks for re- OTTO H. WANDERSEE.
